Abstract

We have studied for the first time the structural change of high-purity metallofullerene (Gd@C₈₂) upon heat treatment in an ultra-high vacuum system (10^-10 Torr) and examined the decomposition product through successive analysis with MS, IR, Raman, TEM, EDS and XPS. It was found that metallofullerene (Gd@C₈₂) had fully collapsed at 580 °C which was lower than that for the complete destruction of C₆₀. The easier decomposition should be ascribed to the encapsulated metal in the carbon cage which could induce the deformation of the C-C bond. The analysis indicated that the broken metallofullerene (Gd@C₈₂) became a kind of graphite-like material with a lot of defects. The Gd atoms leaked out from the carbon cage and aggregated together to form a regular arrangement.
